Application filed October 1, 1913. Serial No. 793,308.

To all whom it may concern:

Be it known that I, JAMES: F. B nn e, a citizenv of the United States,residing at Philadelphia, in the State of Pennsylvania, have invented acertain new and useful Improvement in Pipe-Hangers,- wherein the providea hanger so constructed and arranged that it will properly securea pipeto a wall by the use of one attaching bolt. Such a hanger isparticularly adapted for use in connection With walls of concrete,

stone, or brick, in -whichholes must be drilledto receive any attachingbolts, and

the principal advantage of my improvement is that but one-half ofthe-labor required to effect the attachment of an ordinary hanger tosuch a wall, is required to effect the attachment of my improved hanger.

It is usual to employ expansion bolts asthe means for connecting pipehangers to the hard walls above contemplated, and in practice it isfound that unless means are employed to hold the expansion bolt nuts inthe holes in the wall while the bolts are be ing inserted therein, thenuts are partly drawn out, so as to project beyond the plane face of thewall when the boltis tightened in engagement therewith. The efl'ect ofsuch protrusion of the bolt nuts is to lift the pipe hangers from theirproper bearing upon thewall face and render their attachment insecure.Therefore a further object of my invention is to so construct the pipehanger that it is not thrust away from the wall by'the protrusion of thenut by which:

it is connected to the wall.

As hereinafter described my invention. includes the combination with awall having a circular recess for an expansion nut, extendingtransversely to thewall face; of a split expansion nut includingseparable members seated in said recess and. project-- ing outwardlyfrom said wall face; a pipe hanger including. a base arranged to bearupon said wall face and having a socket registering with the pro ectingend of said nut, and a bolt hole in concentric relation therewith; acurved pipe hook extending from said base and including a,-

web having zeinforcing ribs coextensive withits' -'oppositeedges andfilleted in uni- 'tary relation with said "base';- said hoolnbeingcoextensive with the Width of said base at its junction therewith, andtapered so that its distal end is approximately one-half the width ofits basal end; a pipe extending parallel with s'aidwall face and engagedby said hook; a. tail on said base extending oppositely from said hookand bearing upon said wall face and a singleexpansion bolt engaging saidnut and having a head clamp-v -1ng said base against said wall face;wherebysaid hanger,-pipe andsnut are clamped 1n rigid parallel relationwith said wall face by said single expansion bolt.

My invention includes the various novel features of construction andarrangement hereinafter more definitely specified.

In the drawing; Figure I is a fragmentarysectional view of a wall.showing a convenient form of my invention applied thereto. I

Fig. II is a fragmentary face view of said wall and the form of myinvention shown in Fig. I.

In said figures the concrete wall 1 has the circular and 'conoidalrecess 2 extending with its axis at right angles to the wall face 3 toreceive the split expansion nut 41 including the two "separable members5 which are oppositely counterpart and hingedly connected by lugs 6which are arranged to rock in notches 7; each of said members 5 having alug 6 upon one side and a notch 7 upon the other.

The pipe hanger 8 includes the substantially circular base 9 arranged tobear upon said wall face 3 and having the nut socket ll, registeringwith the projecting end of said nut, and the-bolt hole 12 in concentricrelation therewith. Said socket 11 is of such shape and extent as topermit the protrusion of said nut from the wall without lifting thehanger from its bearing upon the wall face-3. The circularly curved pipehook 14 extends from said base 9 at one side thereof, being coextensivewith the width of said base at "its junction therewith, and includes theweb 15 having the reinforcing ribs 16 coextensive with its oppositeedges and filleted in unitary relation with said base.

Said hook is tapered, as shown in. Fig. 11, so that its distal end isapproxi mately one-half the width of its basal end 'face 3 by saidsingle expansion bolt 21.

and-is curved to hold a pipe 19 between said wall 1 and hook 14 withsaid pipe extending parallel with said Wall face 3.

Said base 9 hasthe tail member exj tending oppositely from said hook andbearing upon said wall face 3 so as to brace said hook 14 against thepressure of said pipe, and the single expansion bolt 2-1 which is soshaped in correlation with the nut as to separate the members 5 of thelatter, as indicated in Fig I, has the square head by which it may beturned and by which it clamps said base 9 against said wall face 3;whereby said hanger, pipe and nut are clamped in rigid relationwithisaid wall Although I have shown a pipe hanger having a nut socket11 so large that the nut at does not engage the hanger; it is to beunderstood that a hanger made in accordance with my intenton may have. anut mately one socket so constructed and arranged in relation to the nutas to engage and prevent the rotation of the nut, although permittingthe latter toprojectfrom-the wallto a variable degree without disturbingthe bearing of the hanger thereon.

I donot desire to limit myself to the precise details of constructionand arrangement herein set forth, as it is obvious that :yariousmodifications may be made therein without departing. from the essentialfea-' tures of my invention as defined in the appended claim.

I claim:

A pifie hanger including' a substantially circular base arranged to,beanlupon a plane wallnfac e and havinga socket 111 'itsi'b earing faceand a bolt hole in concentricrelation therewith; a pipe hook extendingfrom said base and coextensive with the "width thereof at its junctiontherewith, including a web having'reinforcing ribs coez itensive withitsopposite edges and filletedr-fin uni tar'y relation with said base;said book be;
